Married filing jointly: Has anyone tried to combine or merge two different individual returns into a single joint return the following year using TurboTax import feature

[Texas Roger · Accepted solution]

You can't do that. There is no way to transfer information from two prior year tax returns into one tax return for the current year. You can transfer one tax return from the prior year but must manually input information from the other tax return.  If one of the returns is very complicated, that is usually the one that would be best to transfer.
