Thanks to all of you for posts dealing with this issue. I have followed up on the last post indicating Info Wks Section V. I find that the date does indeed track that entered on the “How Do You to Pay Your Federal Taxes?” I am certain the date meets the criteria specified by the IRS. I submitted electronic submission four times and it is rejected every time with FPYMT-071-01. I think I will send a payment to the IRS and submit the amended return electronically without a pay date. I think there is an issue with TurboTax Deluxe for the Mac.
