Pull up all your tax forms by going to FORMS at the top of the TT dashboard. You'll see on the left column of the screen all your tax forms. Scroll down and you should be able to see both 1116 and (one) 1116 worksheet. I use the download version of TT premier; I suppose it's the same for the online version. TT factors in your income to come up with how much credit you are allowed to take in the current tax year and the remaining amount is carried forward.
