Maryland - how long does it take for my tax return to be accepted??

So I filed my taxes early probably in the beginning of January. It is now February 12th which is when they are supposed to be processed. The website says they can take up to 3 days but I read somewhere else that it is processed the same day. It also says it is updated once a day at 10:30 a.m. however mine has not been processed yet. Can anyone with any knowledge tell me how long it usually takes for Maryland state taxes to be accepted.
