After you file

Thanks TurboTaxBillMc! that is a great help.

another questions:
- if i do amend my tax. I assume that i have to do form 1040X (even thought, I only need to amend my HSA) is it correct? Or I just make copy of my 2017 tax and attach 1099-sa and 8889 form and send them to IRS?
- for the State tax return, do I need to amend my state tax return because I only forgot to include my HSA distribution?

Thanks
