Same exact issue. 1099-K highlighted for review. Spent hours with support, no help. They did send me a link for installed version - after i imported on-line return, i no longer got "review" but Schedule 1 is not generated in the list of documents "ready to efile" list. Weirdly enough, if i force go to Schedule 1, it has correct information filled out. I will do mail file and print Schedule 1 separately. This way at least guaranteed it makes it to IRS. Good luck to every one.
