Thanks for the answer! By "you do not reflect this on the return" do you mean with option 3, even if I pay on today on July 30ith, I should not include this payment in Schedule 3? For i.e. if I own 10 dollars, and I paid 4 dollars before July 15th, and I pay another 6 dollars today on July 30ith, the tax return I file tomorrow should only include the 4 dollars I paid before July 15th in Schedule 3 and still show a balance of 6 dollars?
