safe harbor method for calculating wagering gains from electronically tracked slot machine play - To adopt this method, a taxpayer must note "Revenue Procedure 2015-X" on line 21 of Form 1040.
Then, does it mean that I calculate the gain per session, then report the combined total of gain as one number next to line 21 of Form 1040? Instead of reporting Gross on line 21, then loss on Sch. A?
