Need help with Quickbooks desktop - Willing to pay!

[Tracie Van]

I switched from QB online to desktop because I could not justify the pricing any more. 

I am running into a few issues.

I have two tenants who pay rent three months at a time. I am stuck on how to apply the existing credit, without it being recorded as another deposit. (see lower left corner labeled 'deposit') 

I have more issues and willing to pay for some lessons if anyone is willing and able. Thanks in advance.
