It apparently has never occurred to Turbo Tax that two people might want to compute their tax liability separately even though they file jointly. This cannot be that unusual a situation. Reentering all the data for one spouse to create a joint return is both burdensome and error prone.
I hope Turbo Tax can provide a simple solution for this problem.
Thanks.
See this TurboTax support FAQ for comparing filing jointly versus filing separately when using the desktop editions - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-filing-status/compare-married-filing-jointly-married-filing/L6CJYiJ1S_US_en_US?uid=ltltn78d

Sorry, You can not transfer from or combine 2 returns or accounts. Just pick the return for the spouse that has the most complicated return to enter or has any depreciation or business or more investments. Or use the account/return for whoever you want to be listed first going forward (by the way you can not change the order of the names). Then add the other spouse's name, ssn and info to it.
But if you want to keep the prior accounts separate from the new Joint account then start a new account. Online is only good for one return per account. But you can use the same email address for 5 accounts.
