That was absolutely one of the common mistake dealing with Check books, by doing a bank transaction, you will only affect the check book once either on the debit or the credit, the other account included on the distribution of the transaction will not affect the check book balance.
You cash account should be just fine by now and your AR as well as you have described above. Although, if you go to check book balance inquiry, you will find that the cash account are not in balance with the check book balance. Further illustration on this common mistake can be found Bank Reconciliation - Check book versus Cash Account Balance
Now to get your check balance corrected, you need to consider a corrective transaction on the bank reconciliation module level, to do so, it depends on one of two scenarios;
- In case you want to increase your check balance to get it corrected, consider the deposit without receipt document type on the bank deposit window, which will increase your check book balance without affecting the general ledger.
- In case you want to decrease your check balance to get it corrected, you need to do a bank transaction (decrease adjustment type), the second distribution should be any offset account that you need to delete after posting the transaction. Additionally, before posting the decrease adjustment, make sure to stop the (post through general ledger option) in order NOT to affect your cash account balance on the general ledger level
