unallowed depreciation on home business from prior years

I have discontinued my home business the end of 2021. I have depreciated the home office over 12 years, however the last 3 years the depreciation expense was not allowed.  It amounts to about $14,000 that isunallowable.  This year I have converted that home office plus more space into a residential apartment.  This is in my personal residence and I still live here.  I want to convert to personal us as of January 1,2022. and then convert to Residential Rental Property.  what do I do with the unallowable  depreciation amount.
