Estate Tax Question

I'm using TT Business 2024  to file the federal income tax return (Form 1041 for Estates and Trusts) for a person that died in 2024.  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 and where do I find it?
