i have a large home office carryover loss of excess depreciation, will i have to pay 'recapture depreciation' tax for these carryover loss when i sell my house?

i have a home office in my primary residence. The self-employment business has been showing a loss so not all home office depreciation can be deducted. and I am seeing a large number in "carryover of prior year excess casualty losses and depreciation" (form 8829 line 31). For the sake of easy discussion, let's say it's $10,000

My question is, when I sell this house in the future, will I have to pay 'recapture tax' for this $10,000 'carryover of excess depreciation'? will this $10,000 be treated as 'allowed/allowable depreciation', regardless i actually took it or not, i will have to pay tax for "recapture depreciation" for this $10,000? 

and if yes, how do i fix that? file multiple amendments for past years to remove home office? to change it to 'simplified deduction'? i moved into this house for less than 3 years, so should still be able to file amendments for all past years.

No.  If you were never able to take it, that amount won't affect the gain when you sell the house.
