Form 8829 incorrect calculation

Line 40 Business basic of building = 41,249

Line 41 Depreciation percentage = 3.1747%

Line 42 SHOULD BE 1,309, just like 2019's return.  However, Line 42 shows 26,756, causing lines 30 and 44 to be incorrect also.  I tried to change the entries on the form itself, but appears to be blocked.  This appears to be a calculation error in the application.  Please advise if a future update will correct.
