Nap help

Ftm- My 5 month old has been taking really crappy naps since covid started because we are stuck in our house all day. She wakes at 7 i feed her and put her back in her crib she plays for lil then naps for about 40 min

her next nap is at 11ish - she used to sleep for about 2 hours now we wake up after 1 hour.

Her next nap is at 330 and she will only sleep for 30 min! I cant get her to nap pass 4pm!!

I feel like an awful parent because by bedtime 730/8 she is a wreck red eyes crying squirming . Is this enough sleep in the day time naps? Pushing up bedtime doesnt work with our schedule. I dont know what to do but i feel like this nap schedule is not healthy? Or is it ?
