After you file

They said you CAN start filing on 1/3/17 ... no where do they say you MUST file ASAP.  Users are the reason the program is put out early because you demand it and will buy it and they can make money.  Also if you file with them you are locked into them so you can't file elsewhere ... Profit is a strong driver.  

I am fairly sure that the wording in the instructions tells you that it is 48 hours from IRS accepting the return ... in fact it only takes minutes to get an acceptance with the new IRS system.
