Folks, its clear this is something TT may not fix in time. For the downloaded MacOS version, the Tax and Interest Worksheet (that populates the Mortgage field (Schedule A, Line 8a)) remains a User Entry field.
Since TT reports only the Schedule A to the IRS, and none of the worksheets or 1098 info we enter accompanies the filing, I suggest you all calculate your interest deduction based upon one of the two or three ways mentioned in this thread. Enter this amount in the Tax & Int Worksheet/Mortgage Interest Limited Worksheet. It will be reflected on your Schedule A. For those of you worried about audit flags, keep in mind that what you enter will be substantially less than the sum of all those 1098s reported directly to the IRS (assuming you calculated correctly), so most likely SWAT teams will not be arriving at your home.
