Hello @Zhaoja1 ,

If you read a post or two above, I explain that it is OK to have funds in your undeposited funds at year end.  It simply is a "holding" account for funds that have been received (in your possession) but not yet deposited to the bank.

Now if you have an amount in your undeposited funds at year end but you don't have any payments to deposit, then that is a problem that requires investigation.

The undeposited funds account is basically a clearing account whose balance rises and falls throughout a normal accounting period, usually resolving to $0.00.  However, at month-end or at year-end, it is not unusual to have an amount in there as everyone is not going to rush to the bank just to get their deposits in by month end or year end.
