I was having the same issue. However, when I went to try the suggestion of signing in on the desktop, I saw that I was signed in already. So instead, I signed out. At that point, the problem went away and I was able to import the data. Bottom line is that it seems that there are some conflicts with being signed in or out that is conflicting with ReCaptcha's verification process. Hopefully in the near future, TT addresses this so we don't have to go through all of these attempts to access our imported data.
