Car seat angle not right. Need help.

I’m almost 36 weeks and trying to get my car seat ready. I’m a FTM so I want to make sure it’s safe.

So I’ve anchored my car seat and made sure the setting was all the way leaned back. But even with the setting leaned as far back as it will go, now that it’s anchored I don’t think it’s leaning back far enough? The “rear facing level line” on the back of the car seat isn’t quite level. It’s super close but I want it to be perfect. I guess my seats just scoop too low so the car seat can’t get all the way level? I even moved it to the middle seat because it sits up higher.

I don’t know what to do 😕 Is there anything I can do to prop up the front up it to leave it back further that is safe? Or anything else I can do?? Please help me...
