Ah, ok, that makes sense.

So, I need to split out everything manually, which I have mostly done. I'm struggling with the W-2's, though. Splitting wages & federal income taxes is easy enough, but what about SS & medicare wages/taxes? What about all the items in Box 12? Am I splitting all of that as well?

Also, to get the income of the spouse 1 onto spouse 2's return, I'll be entering that 1/2 W-2 there, even though spouse 1 never worked there?

Thanks, this helps immensely!
