Is it okay to have 2 accounts attached and categorizing the transaction the same on both accounts?

Thanks for posting here, eric-nationwided.

Allow me to help you in categorizing your transactions.

You can connect multiple banks and credit card accounts to QuickBooks Self-Employed. However, we're unable to add and categorize a single transaction to more than one account. This is to avoid duplicates and to maintain the accuracy of your data.

In addition, please note that each category has a corresponding line on your Schedule C. For your reference, here's how to categorize a transaction.
