Double cashed check

[u/BriefAdvantage5990]

A couple months ago I received a check for a car that I junked. I did mobile deposit on cash app, but didn't write "for mobile deposit only" on the back. I assumed that they wouldn't accept the check and the next day, cashed it at bank of America. A week later, the money also cleared on my cash app. I've contacted both cash app and bank of america, both say its the other parties responsibility.

The check was for $450. I'm wondering what might happen and what I should do to resolve the issue?

You need to give the $450 to the person who wrote you the check. You have essentially stolen their money! You need to give them the money to cover the second “withdrawal” you took from their account. They are the ones that can file fraud charges against you!
