How to report taxes paid online?

Your software will have someplace to tell it how much you paid in estimated tax payments, and when.

If your software switches between Form and Input views, go to the estimated payments line on the back of the 1040 and switch to the input view.

I use H&R Block - aka Taxcut It has a major section - Federal Tax Payments - with four principle choices. One is Estimated Tax Payments for 2010. When I select it a panel is presented allowing entry of Dates and Amounts. The Amount gets added into any other amounts already at hand (W2 etc.) Your software almost certainly has an equivalent capability. Would that work for you? Geo.

Actually the estimated amounts and the W-2 amounts are not added together on the 1040. Rather they are on separate lines of the 1040.

Exactly what type of tax payment did you make? If an estimated payment, others have answered that surely your software has a full-blown screen for that.

Do you mean your balance due? Normally your software will ask you if you want to direct debit your balance due or send by check. Just choose "send by check" if you have used some alternate method to get your balance due to the IRS.

How would you tell your tax software that you made a payment via a check? Its no different regardless of how you pay.
