I took a ROTH IRA withdrawal back in 2023 and one in 2024. I had already filed my taxes for 2023 but did not receive the 1099-R form until after I received my refund. Once I tried to amend/add it to my return, it showed I owed money. I was under the assumption a ROTH IRA account is already pre-taxed so why would I have to pay taxes again on it'?
