I have an annoying bug that has been around for several years. In checking for errors, TTax Business always flags an error: "Grantor trust box is the only 'Entity Type' box checked. If the entire return is a grantor type trust, do not report dollar amounts on Form 1041".
The only dollar amount are 0's (zeros) populated by Turbo Tax. I believe I tried (in years past) to override the zeros by deleting them, and got more errors, so I leave the form as is.
I have always ignored the error, and the IRS accepts the return. Just a little annoying for all these years.
