Official instructions for 2022 PA Schedule E, emphasis and italicized statements are mine: ref
LINE 18 (expenses)
Add the amounts on Lines 3 through 17 and enter the result for each property.
LINE 19 (income)
If Line 18 is smaller than Line 1 (rent received) or Line 2, subtract Line 18 from Line 1 or 2 and enter the result for each property.
LINE 20 (loss)
If Line 18 is greater than Line 1 or Line 2, subtract Line 1 or 2 from Line 18 and enter the result for each property and fill in the oval. (TurboTax is not doing this!)
LINE 22 (net income or loss)
For all properties answering “No” to Section II, Line c, add the amounts for Line 19 and 20. If a net loss, fill in the oval. (impossible to have a net loss in TurboTax!)
