Sale of Home/Home Office Depreciation and AMT Depreciation

Hello, 

 

My husband and I purchased a home before we were married in 2017. We married in 2019 and sold the home in 2022. We did not earn more than the $250K/individual or $500K/joint to have to pay taxes or report that. We have not received a 1099-S. 

However, we filed separately for a number of years, my husband claimed the home office credit. For 2 years we filed jointly, he also claimed that credit. 

Now, if we file separately for 2022, how do I report this? 

Also, where do I find the numbers to total up the Depreciation on previous tax returns? Where do I find the numbers to total up the AMT Depreciation on previous tax returns? How do I know we used these credits, multiple times our expenses on the home were more than his earnings.
