SC state tax website shows balance due that is slightly different than TT (Desktop)

Hi,  I filed my federal and state taxes electronically about a week ago.   I live in SC.   When I log into the SC state tax website it shows my balance as being ~$4.35 higher than what TT showed as what I owed.  Not a big deal but wondering if others have seen this type of discrepancy?   I know that the balance showing on the SC website doesn't include a past due/open balance since I checked the website prior to filing, and it showed a $1K credit which was the amount of my prepayment. 

 

Regards,
