A child/baby does NOT have to be "entertained" every second/minute of the day. So you don't "have to" turn on the TV, to "entertain" a child. Although I know sometimes we Moms do that, when we are busy and to keep our child occupied.
Just leave the TV off.. .and it gives the child a chance to amuse themselves... which is a very valuable thing for a child. "Play" is important for them... which also includes them exploring without being told how to play. At this age... just keep safety in mind... but let her just hang-out and learn self-motivation/self-reliance and just "knowing" that its okay. Lots of child experts say that over-stimulation can also be not good... and letting a child just play without being told 'how to' play, is just as important. And it doesn't make you a "boring" Mom.
Even just a pile of crumpled up newspapers, with toys hidden in it, it TONS of fun for a baby this age. LET them make a mess and tear up the paper and rummage through it.
"Play" things does not have to be store bought. Let her play with empty boxes, or wooden kitchen utensils, or a Kleenex box and her pulling out the tissue one after another (my kids loved that). Or, just lay out in the yard on a blanket and stare up at the sky... and just talk to her about what you see, describing it. My kids loved that too. Or we'd just lay out on the yard and I'd read a magazine while they hung out and amused themselves by pulling at the grass, or touching leaves, or exploring textures of nature, or "smelling" flowers and leaves. Get finger-paints and put her in the tub and let her go at it. If its messy so what- she's in the tub and you just rinse her off after. That is what I did with my kids when they were 1 years old. They LOVED that. Or, give her paper to paint on. Its good for them and for their fine-motor skills too. And than talk about the colors to her. Turn on some music and hold her and rock/hop to the beat... or thump your hands on a box to the tempo... teaching her rhythm and music appreciation and fun etc.
Anything really, amuses them at this age. Or as you go about your own routines/chores, just talk to her about what you're doing, and let her "help" you. Kids LOVE that. Or roll balls around back and forth.
Really, you do NOT "have to" fill up the whole 8 hours for things for her to "do." And, it is really stressful upon a Mom to see those hours as having to be filled up with activities every waking moment. (wink). Some days, I just hang out with my kids and THEY invent things to do themselves, too. Which is a good developmental thing for them to do, too. And you will then "see" what your child's OWN interests are... and talents.
All the best,
