I am trying to file an amended 2023 tax return because I received an additional 1099. When I bring up the old return it shows the correct old refund, but when I amend it, it puts incorrect AGI and incorrect overpayment in Column A. Why is this happening? and how do I correct it? The 1040-X produced by TurboTax is NOT correct and cannot be used.
