When filing out other self employed income what do I put under type of income when the payments are made by credit card?

I own an online clothing store. All payments are received through credit card payments.  When filing out other self employed income what do I put under type of income? although I can type what I want, the choices turbotax pre-fills are (checks, cash, 1099-K).

Payments you received by credit card have to be reported as income.

The payment types in TurboTax are listed as examples of the types of payments. You can enter your credit card payments on any line. All types are added together and reported as one total on your tax return.
