If this house was a rental property when the improvements were made, then no. The cost of major improvements would need to be reported in the year in which they occurred and depreciated over time. If you didn't depreciate these improvements and they didn't qualify for immediate expensing, you have some work to do based on the missed depreciation (I'm assuming that the house was a rental property from 2010-2019). You can only amend a return back one year to account for missed depreciation. Otherwise, you will need to use Form 3115 to obtain the IRS's consent to claim the missed depreciation. This can be a very involved process, and you may need to contact a local tax pro to help you with the missed depreciation.
Not filing Form 3115 and just eschewing the missed depreciation is not a good option, either. Depreciation allowed or allowable will be recaptured; that means that even if you didn't take the depreciation deductions, you may still be taxed on them in the form of depreciation recapture when you report the sale.
If this house was NOT a rental property when the improvements were made and you later converted it to rental use, then you ideally would have already added the cost of the improvements to the cost basis of the home. If you didn't, please see above about Form 3115.
