Hello there, @rae2586.

Let's go to the bank register to delete the deposit from there.

But before we proceed, I suggest seeking help from your accountant if doing this won't affect your books.

To start with, you can follow these steps on how to delete deposit:

1. Go to Banking.
2. Select Use Register.
3. Choose the Bank Account, then click OK.
4. Find and select the deposit transaction.
5. In the toolbar, click Edit.
6. Hit Delete Deposit.
7. Click OK to confirm.

Once deleted, you can re-enter them as bill payments and create a vendor credit. But please make sure that you've entered it correctly. 

Here's how you can do it:

1. Click on the Vendors menu.
2. Select on entering Bills.
3. Click on Credit.
4. Fill in the necessary information.
5. Click Save and close.

Once done recording/creating the vendor credit and the vendor bill correctly, you can now open the bill and pay it.

1. Open the Bill.
2. Click on Pay Bill.
3. To apply for the vendor credit, click on Set Credits under the Number of Credits section.
4. Click/select the vendor credit under Discount and Credits.
5. Click Done.
6. Click on Pay Selected Bills.
