Proconnect estimated taxes posted when not paid

My client received an IRS notice saying she owed over $8K more. I couldn't figure it out at first as the numbers matched except for the estimated taxes. Went to the Est. Tax input screen I posted showing the client paid 1st-3rd quarter and NOT the 4th quarter. The client did not pay the 4th quarter so only the memo section was complete. Therefore, this 4th qtr should not appear as paid on the tax return.  I added the numbers up that were posted and it was $24K, However, when comparing to the tax return the estimated payment show $33K as if the payment was made.

My question is has anyone else have this happen? I contacted the customer service chat and she was absolutely unhelpful and could not understand the concern, even after sending her the tax return. She just kept insisting it was correct because the estimate screen showed no payment and the client didn't make the payment. I could not get her to understand the issues was a coding error in the software because it should not have put $33K on the tax return itself. I am stuck trying to explain to my client why she has penalties and the dilema is I will have to eat it while it is an intuit error. Now i am left wondering how many more returns this may have happened to!
