Can "unused" deductions for cost of repairs and depreciation for the year they occurred be carried forward to subsequent years, and is there a limit for how many years it can be carried forward? Also, if the rental property - or in my case just a room in my house that I rented out - goes out of service for a couple yeas, and then reenters service - lets say in 2023 - when I do my 2023 taxes can I carry forward "un-used" deductions for depreciation and repairs/expenses from 2019 and 2020 and apply/claim them in 2023 so long as they were reported when doing taxes in 2019 or 2020, or they were reported by amending taxes for the years 2019 and 2020?
