Have you looked at your return using the Forms method (in the blue bar at the top, far right; toggles between Forms and Step-by-step), then scroll through the forms looking for a red exclamation mark (!)?
Likely one next to Form 1116 based on your comments. Check on the form with the red ! then click the red "Errors" octagonal box (looks like a stop sign) with an exclamation mark at the top of the column (on the left) for all the Forms. In the open form at the bottom there should/might be an popup explanation of what the issue is. No guarantees though.
As an example, I have a foreign tax carryover from last year and my Form 1116 Comp Wks reads (Not Done). When I open the 1116 Comp Wks and click on the Errors at the top of the far left column a box pops up at the bottom of the worksheet telling me the error is because the carryover "requires Form 1116, Schedule B, which will be available in a future product update." So I get to wait. I have a Schedule H-T also awaiting a final form, that one gives a date of March 17 for release. I do not see a release date for the Form 1116 Schedule B.
Personally, I am more annoyed with Congress making changes to the IRC so late in the year the IRS cannot get the changes reflected in the forms. I am very happy I am not an IRS employee attempting to translate Congressional legalese/gibberish into a form that actually works. Mostly works. If the Form delay is not due to Congressional tardiness, then I move to being annoyed with the IRS, and if not the IRS that is late then on to TT.
