Beforehand, could you please clarify which checks you are referring to? This will help me provide an accurate resolution to your concerns.
If you’re referring to a paper check, the option to add the check to the bank deposit is unavailable. Instead, you can deposit the check directly at your bank since you’ve already recorded the bank deposit in QuickBooks.
However, if you're referring to a mobile check deposit, you can deposit your checks directly using the QuickBooks mobile app. Here’s how:
Sign in to the QuickBooks Online app on your mobile device.
Go to the Cash Flow section.
From the QuickBooks Checking home page, select Send Money.
Tap Deposit checks.
Enter the check amount (ensure it doesn’t exceed the limit displayed on the screen).
