I am a self-employed piano instructor. My students pay through cash, check, Venmo, Paypal and Square. (I have Venmo and Square business accounts.) I manage all my income and accounts in Excel, but don't note which methods students used to pay. In the past, I've just entered my total income amounts from my spreadsheets to Schedule C. However, when I receive my 1099-K for 2022, some of the income that is already listed in my spreadsheet will be reported on the 1099-K. How do I report the income from my spreadsheet correctly when some of that income will be covered in the 1099-K?
