Hi,
I live in Texas, and my wife lives in California. We jointly own properties in both states. Every year, we need to file three 1040 federal tax returns: 1) married-filing-jointly 1040 for both of us (the real one); 2) my wife's married-filing-separately 1040 to drive her CA state return; 3) my married-filing-separately 1040 to drive my CA non-resident state tax return. It's a pain working on them one at a time and keep them all consistent. Is there a way to work on them in parallel for the same item? Thank you so much for your help!
