I figured out how to import transactions from my Apple Card, but how do I change the transaction from cash to credit card?

Welcome to the Community, @danstratton-iclo. Thanks for letting us know about your banking concern.  

I appreciate your effort in importing your transactions from Apple Card. Please know that it is still unsupported in QuickBooks Self-Employed (QBSE). Though you can still import them, it will fall under Cash Account. However, you need not worry about your federal estimated tax as accounts won't affect those calculations. 

You'll want to check out this article for more insights about manually importing transactions into QuickBooks Self-Employed.

I’m always around to guide you more with your banking and transactions concerns. Take care!

That simply isn’t going to work very well. Because my checking account shows payments to my Apple Card credit card and my manually imported Apple Card cash account also show payments, so I end up showing double payments. One to cash and one to a credit card. Now I understand that this really doesn’t matter, as I am only categorizing the outgoing expenses, but it is a mess. A better solution would be to be able to change the cash account to a credit card account.
