Responses are geared to the tiny proportion of filers who conducted business transactions involving virtual currency. Since it was salient to them, they would have focused on this issue in the course of completing their returns.
I am one of the 99.999% of filers whose income and deductions did not involve virtual currency. As a result, the first time the issue arises is when an error is found in the final review of the return, just prior to filing it. It comes completely out of the blue and requires time and effort to learn about and deal with the issue. The error message is so vaguely worded that it is unclear what is being asked and what is the appropriate box to be checked. TT should provide more information to the many customers who will encounter this obstacle to filing their returns.
