@Jbizz510 If your first W2 return was Accepted from Cash App or somewhere, THEN you have to file an AMENDED 1040X return to fix it and add the missing info. Go back to Cash App and see if you can amend there.
Even though you filed with Turbo Tax first, it sounds like the Cash App return got accepted first. That's why Turbo Tax is rejecting. You can only file 1 return.
