How do I change a manually added cash transaction to a credit card transaction?

Manually added transactions are automatically posted under Cash, mbarber86.

You'll want to import your historical banking transactions as a CSV file so you can select a credit card account. You can also look for a third-party app that can help you convert the PDF bank statement into a CSV file. 

Once converted, I'd suggest following these steps to import the file:

1. Go to the Gear icon in the upper-right hand corner, then select Imports.
2. Look for the correct account and click Import older transactions beside it.
3. Select Browse and look for the CSV file. 
4. Click Open, then click Continue.

For further guidance, please see this article: Add Older Transactions to QuickBooks Self-Employed.

Once done, I encourage categorizing the bank transactions. This way,  QuickBooks will put them on the correct line of your Schedule C. 

I'll be glad to help you again if you have more questions about importing your bank transactions. Please ensure to add the details in the comment section. Have a good one.

Hi mbarber86,

Hope you’re doing great. I wanted to see how everything about changing your cash transactions to credit card transactions. Was it successful? Do you need any additional help or clarification? If you do, just let me know. I’d be happy to help you at anytime.

Looking forward to your reply. Have a pleasant day ahead!

I have an Amazon transaction that covers two invoices. On the advice of the forum I have excluded this and added two transactions for the two invoices to take its place as you cannot attach two invoices to one transaction. However, on doing this the transactions are automatically coming up as cash transactions. How do I change this to be from my business bank account?

It's my pleasure to assist you today, Edmond.

Base on your situation, you'll want to consider using the Bank Rule feature in QuickBooks Online (QBO). This helps you save time by setting up an automatic categorization of the regular recurring transactions. These rules are a way for you to ask the system to prefill some information when transactions are downloaded from the bank.

1. Go to Bookkeeping and select Rules.
2. Click New rule.
3. Enter name in the What do you want to call this rule? field.
4. Fill in the necessary information.
5. Select Save.

QuickBooks automatically applies your rules to transactions in the For review tab. These are the ones you need to review every day.
