Sale of primary residence

My deceased husband purchased a home in 1992 for $145,000.  We were married in 1995.  In 2018, my name was added to the deed ( joint tenants with right of survivorship ).  My husband passed in 2019 and in 2020, the deed was transferred to me.  I do not have the original paperwork from the initial purchase.  I obtained the purchased date information from the county website.  I sold the house in 2022 for $375,000, so the gain was less than $250,000.  Can I use his purchase price of  $145,000 for the cost basis when making those calculations?  Do I have to report the sale on my 2022 Federal Income taxes?
