WHEN POSTING A DEPOSIT FROM A SUPPLIER WHAT WILL I PUT IN ACCOUNT COLUMN?

Greetings, user38253, 

Are you referring to your Bank Deposit page? If so, I'd recommend reaching out to your accountant so they'll be able to verify what appropriate account you can use when recording a deposit. This is also to make sure that your books are recorded properly.

I'm including these articles to learn information about account register in QuickBooks Online for your reference:

• What are account registers in QuickBooks Online?
• Add transactions to account registers in QuickBooks Online

• What are Bank Deposits in QuickBooks?

I'll be right here if you need more help.
