I bought the house in 1998 and it was my primary residence til 2010 when we got married and I moved to her house.
At that point it changed to a rental til we sold it in 2020.
I understand that I can deem it my principal residence up to 4 years after I moved out and changed it to a rental.
Turbotax is splitting the capital gains between my wife and I, but then asks how long it was a primary residence. I believe I should state year of acquisition was 1998 and I deem it my primary residence for 16 years? (1998 to 2010 + 4)
But what do I put for my wife's form as it was never her primary residence - but do we 'deem' it her primary residence til 2014? Do we have to have the same timeline for principal residences or can they be different for husband and wife?
