Posting for anyone else that runs into this problem later. Unfortunately the instructions posted were the same that I had found but had not worked for me. An import button never appeared, and searching just sent me in a loop. I finally found the solution by turning off my VPN (which stopped the continuous looping) and going to the section indirectly through Its Deductible rather than TT. On ItsDeductible click the link on "how to import" > Online > Jump to Link. The import link magically appeared. It never appeared when going directly through TT nor when my VPN was on.
