How do I find my total payment and withholding from the previous year?

[cameaf]

The total payments that you had for prior year can be found in your printed forms in the "Payments" section of Form 1040. The payments section includes the withholding amount. Based on which form 1040 was used, you can find the withholding amount on:

Form 1040 - Line 64 

Form 1040A - Line 40 

Form 1040EZ - Line 7
