Can I import my 1098 (Mortgage Interest Statement) like I did in the past?
Not any more. Manually enter your mortgage statement by searching for 1098 inside TurboTax, clicking the "Jump to" link, and following the onscreen instructions.
Note that lenders aren't required to give you a 1098 if you paid less than $600 in mortgage interest last year. You'll still want to enter the deduction though. Contact them to find out how much mortgage interest you paid, and then enter the info as though you had received a 1098 for it.
