I followed these instructions and was able to find where it jumps to the "1099-NEC" page directly. In the income section, it only listed two 1099-NEC entries (one for LYFT, one for UBER) but on the "jump" page, it showed 4 entries, and one was still blank. Apparently the system was retaining information that was not being shown, but prevented the Schedule C from generating.
I deleted the 2 redundant entries and verified the information on the remaining 2. Success! I was able to complete the e-file for both Federal and State, and hopefully all is well.
Thanks again for the help!
