That's not the point. The software should not count on you to fix its shortcomings. If you don't know to look for it (and any other flaws in the software) then you might miss it which will cause issues either on the current or future returns.
This is actually the second issue I had with this area of the software. The first was several years ago when I was earning tax credits for low-income housing investment. In one of the years I didn't earn any credits. The TT software said that I could use $7,000 in credits. That was true, but I hadn't earned any new credits that year. The software proceeded to tell me that the carry-forward credit was what I had coming plus the $7,000. After much back and forth, I reported the TT statement to the IRS along with how it should have worked. TT's statement was "we stand by our program". I guess I should have just taken (i.e. stolen) the tax credit from the IRS.
