I suspect TT will update prior to the date the IRS opens the filing window on January 27th. This affects almost everyone who files! TT tends to update their software on Wednesday nights into Thursday mornings.... suggest patience as you can't file until the 27th in any event. look at line 30 on Form 1040 as that is where the additional stimulus will reflect. you will simply be asked how much you received on the 1st stimulus and then the 2nd and TT will figure the rest out.
