After you file

Sorry, the links do not provide any support for the problem of the Intuit software DELETING user TAX DATA.

Nor is there a telephone number to contact to get real answers.

This public forum should be informed as to how well Intuit supports their TurboTax product.  Even if I can't get support or advice here for the software issue, at least I am being counted among the other (hundreds, thousands?) users who have experienced the same.

As of today, it appears that I will need to re-add all of my 2020 tax return data in order to file and Amendment precipitated by inaccuracies in the TurboTax software.
