Hello. I just found out about this tax change and I already filed my Fed and VA state returns. I received my refunds last week. I only noticed when I opened TurboTax and the amount at the top for VA State return was different than the amount I initially filed for and received. When I opened TurboTax Home/Biz it must have updated when the tax change occurred (which was after I filed.) When I look at the forms in TT, it now shows my state return with the new return amount with line item addition for the med. So, I guess what I'm asking is...all of the 'amend' instructions on the TT site don't address when the program has automatically updated my forms and return amount AFTER I have filed. If I do a 'save as' of the file, it's as if the return was filed with the tax change. Thanks for your assistance.
