Changing Critical Depreciation Fields - Tax Book

SUGGESTED

Due to the CARES Act, qualified improvement property that previously was 39 year and bonus ineligible is now able to use 15 year and 100% bonus. I have some QIP property from 2018 that I would need to change critical depreciation fields to update. How can I do this while maintaining the original 2018 ending balance? Essentially for 2019 I need the reports to reflect the catch-up depreciation values from the 2018 bonus that was missing and is now eligible, but I do NOT want to change depreciation that was recorded in 2018.

Context: I already ran 2019 depreciation for this company in Feb, before CARES was passed, with the following specs. Now I need to change this QIP to MA100/15 year/100% bonus:

Placed in service 07/01/2018

Aquisition value: 75,632.17

Depreciation Method: MF100

Estimated Life 39 years

Prior thru date 12/2018

Current thru date: 12/2019

Depreciation this run: 1,939.29

Current Accum: 2,828.13

How can I update such that my "prior accum depr" for this asset in 2019 still matches the "current accum depr" I originally calculated in 2018?
