Form Not Reported

I've completed entry of three 1099-MISC forms. One of the three prompts a "review" screen:  FORM NOT REPORTED: Your Form 1099-MISC from [Company] shows $$ on line 2, but this income is not reported on another form or schedule.  Let's review your entries now so you can tell us where to report this amount on your tax return. (CONTINUE) After confirming all entries [Box 2: Royalties] [Box 17: TX] [Box 18: $$].

 

Why does this 1099-MISC "need" to be entered elsewhere?  Others do not.

Is it because it is the only one with STATE information provided?

If so, is it because the state reported [TX] is not the state where I live and file state taxes [ID]?

Does TurboTax expect me to file a TX State return for this income, which I believe is well below the threshold for filing a state tax return in TX?
