Deductions & credits

What would my tax situation look like if my ex spouse finally sold our Indiana marital home in May 2019 but I the ex-wife and co-borrower had not lived in it since probably September 2013 due to a divorce now live in California missed the 5 yr primary residence question due to this...

also we purchased the home in March 2009 for 105,000 and he wanted to sell the house to a friend of his & buy a new house asap for him & his new wife so he insisted that if I wasn't a horrible greedy person we must sell it for 80,000 although I did get him to raise the sales price to the $105,000 that we originally purchased it for even though it was worth closer to 130-140k.

                                   (he had been living in the home with as his girlfriend (now 2nd wife) since months after our divorce in 2013 in fact I had decided to visit family out of state for a few weeks before our divorce was finalized thinking it would take some months to process.he wouldn't even allow me to come pack my belongings myself after I visited family out of state for a few weeks before our divorce was finalized 

 

 

I am on SSDI and disability retirement and got 40% of the proceeds so about 42k on the tax document & 9k of it is profit after the mortgage was paid off  I realized that although I was a co-borrower on the mortgage and he could not originally assume the loan on his own the 1st 2-4 years after our divorce that the mortgage interest statement also only has his ssn on it and his new address and I was not issued a separate one with my 40% portion & his 60% portion on his 

 

it irritates me because he agreed to sell the house within 1-2 yrs of our divorce originally & then kept coming up with excuses for not doing so and I am afraid of owing taxes that I now may not be able to afford due to the situation he kind of helped push me into since he knew I was in no situation to be able to sue him to sell it until he was good and ready to on his own terms.

 

 

unsure of what amounts I use on my taxes that are due today...
