I've amended my Virginia return to add federal tax exempt income from states other than Virginia that was not included in my original filing.
Two Issues:
First, in the original return I credited my entire overpayment amount to next year's taxes. The overpayment amount is now smaller (say a $1,000 overpayment) due to the additional Virginia income and I continue to want to credit the entire amount ($1,000) to next year's taxes. The Virginia tax forms appear correct. BUT the Turbo Tax File by Mail instructions double the overpayment amount ($2,000) and indicate that half ($1,000) is to be credited to next year's taxes and the other half is to be refunded to me. I have no idea why there is this inconsistency between the file by mail instructions and the actual amended return.
Second, TurboTax provides the option to file the amended return electronically but I thought I read that TurboTax does not support electronic filing of amended Virginia returns. Also, I am hesitant to file electronically in view of the first issue I mentioned.
