Am I correct that if I add my spouse to my return and then we decide to file separately it will be easy to remove him? I won’t have to wipe everything and start over?

No, that's not correct. It's nearly impossible to cleanly remove a spouse from a joint return and change it to separate. Changing from separate to joint and then back to separate is pretty much guaranteed to cause errors in the return the you won't be able to fix. You should start the return over from scratch. Or you could use different TurboTax Online accounts for the separate and joint returns, then pick the one you want to file. Just be careful to keep track of the different accounts and passwords.

What you're trying to do would be easier with the CD/Download TurboTax software. You could create your separate return, save a copy of it with a different file name, and add your spouse to the copy.

Just to add--after the April 15, 2019 filing deadline you will not be able to amend a joint tax return to switch to filing as married filing separately.  So do your homework now and determine which is better before you file.

Thanks for your answers! I actually have fairly simple taxes, so I might just make note of what I've entered, then if I add my spouse and we decide to file separately, starting over shouldn't be too bad. But at least I know what to expect before I start. Thank you!
