In 2020, the IRS revised the worksheets used to calculate the rental deduction. See Publication 527, page 21 for details. The data entry and worksheets used in Drake20 are the same as in prior years, with the addition of the line 2b worksheet printed at the bottom of the Wks Schedule E Personal, if applicable.

If the rental was also the taxpayer's main or secondary home, however, the non-rental portion of the deductible mortgage interest may also be deductible on the Schedule A, line 8a. If this applies, the check box Taxpayer's main home or second home must also be marked for the software to carry the remaining amounts to the Schedule A. In this scenario on the Wks Sch E Personal worksheet, both lines 2a (rental portion of deductible mortgage interest) and 2b (rental portion of real estate taxes) will be calculated using the tax court method and all remaining deductible amounts carry to the Schedule A.
