Can someone please tell me how to upload my payment receipts for my self employment to show proof of my self employment wages

Did the IRS ask for it?  You just enter your total income from your own records.  If the IRS wants to see proof they will send you a letter.  That's when you give them your deposits and receipts.

To report your self employment income you will fill out schedule C in your personal 1040 tax return and pay SE self employment Tax.  Here's a Schedule C  https://www.irs.gov/pub/irs-pdf/f1040sc.pdf

You can enter Self Employment Income into Online Deluxe or Premier but if you have any expenses you will have to upgrade to the Self Employed version or use any of the Desktop CD/Download programs.
