How do I find my U.S. Federal Tax Paid

You can check your tax account on the IRS site.https://www.irs.gov/payments/view-your-tax-account

Or check your own bank/credit card records for the amount you paid the IRS.

Or do you need a number off your tax return ?

I need a number off the tax return.

Then look at your  form 1040 ...line 63 says total tax.

How did I setup to pay my Federal Taxes
