Why does TurboTax Business 2023 say I am required to file a state business income tax return for an estate in Texas?

I'm using TT Business 2023 (desktop version) to file the final  federal income tax return (Form 1041 for Estates and Trusts) for a person that died in 2023.  The return is very simple, having one income item (Schedule K-1) and one deduction.  After completing the federal review portion, TT moves to State Taxes where it declares: "This year, you are required to file a state business income tax return in Texas.  This state business return is not available in TurboTax. To complete this return, visit your department of revenue and download the appropriate forms to print or file separately.

To my knowledge and after doing some online research, Texas requires no such return.

Why does TurboTax claim a state return for Texas is necessary?
