State tax filing

Well I found out why It was saying that somebody already filed under my social security number is because I did the  IRS deposit form for the stimulus check before I filed my 2019  taxes with y'all for the stimulus check I didn't know that was considered filing my taxes but I know it says you can fill that form out if you made under 12,000 which I did. So I was told that I have to do an amendment or mail it in I tried to print it to mail it in but I see I have to pay first but I have not received any type of money yet to even be able to pay so should I just wait to do the amendment
