For my situation, these are old transactions, deposits, from when you first started our business and the person who was receiving the payments didn't have the correct banking account picked when receiving the payment and just received the payment.  And when the deposit came over from my back into QBO I didn't know at the time to match the deposits to the payments when adding the transactions so when I categorized the depoist i just clicked categorize and picked my bank name from the drop down menu and clicked add.  So the money that was received into the undeposited funds just sat there and still is.  So now all payments received into my bank name from the drop down menu not undeposited funds.  So I have large negative QBO balance showing and large amount sitting in undeposited funds when looking at the chart of accounts. 

I am still learning QBO since I am finally able to work for the business full time.
