Hi @Bceltic88,

I'd appreciate it if you could provide additional information on this issue, such as the error message itself. 

One situation you can bump into while changing the deposit account is when the payment was already reconciled. You need to press Yes twice to continue.

If you have a different situation, then I'd love to hear more about it. 

I suggest you view this article as well: Record and make bank deposits in QuickBooks Online. It includes the steps on how you can combine bank deposits to match your actual online bank deposits. 

Post a comment below if you have other questions about payments and deposits in QuickBooks Online, and I'll be sure to have your back.
