Napping help! 😡😡

My daughter will be 9 months this week and she sleeps through the night 🙏 but her naps a terrible! She will take a 30-45 minute morning nap and it won’t take too much to get her to sleep, but the afternoons are hell. If we go anywhere she will fall asleep in the car like right before we get home and then she will not go back to sleep when I feed her and put her in her crib. I know she’s so tired because she hasn’t slept in several hours and she’s rubbing her eyes and showing tired signs. She will roll around her crib, cry, swipe the monitor so I can’t see her. I’ve tried her swing which is in her room... it takes me at least an hour to get her to sleep. If she won’t nap she is a tired mess from like 6pm till her bedtime at 8:30. I’m at my wits end with this... help!
