QB Issue Resolution:

If I understand this correctly, there is nothing to fix

you received payments or sales
that amount was posted to undeposited funds
then you made a bank deposit which moved those funds from undeposited to the bank

so in the bank register it showing what account the money came from what the deposit was made

the invoice or sales receipt recorded the income for the sale, and if you sold inventory, that same invoice or sales receipt lowered inventory asset and posted the cost of what was sold to COGS

all is good
