My issue may be identical -- I have the TT Premier version and have used this version for many years with no issue added my 1099 income to schedule C. I expect to receive a 1099 (now 1099-NEC vs. 1099-MISC) for 2020 but TT Premier is not allowing me to add 1099-NEC data to my schedule C. When I enter the 1099-NEC information within TT, it does not move to schedule C. I can only enter 1099-MISC data to schedule C (consistent with past). Is this something TT will likely address in future updates or am I missing something?
