received a form 1125-e. where on my 1040 return would I report this income?

it depends; Form 1125-E must be completed and attached to the Form 1120, 1120S, etc. whenever the total receipts of the Corporation exceeds $500k during the tax year. for example, total receiptd mean :Form 1120S, page 1, line 1a, plus lines 4 and 5; income reported on Sch K, lines 3a, 4, 5a, and 6; income or net gain reported on Sch K, lines 7, 8a, 9, and 10;and income or net gain reported on Form 8825, lines 2,19, and 20a.
