There is no way I will be submitting a copy of my tax return to you or any agents. Given the bugs present in TT, I do not trust that "sanitization" would remove all of my personal and other sensitive information.
Instead, you should create a simple test tax return from scratch to reproduce the TT bug. Start with a single filer with one W-2 with insufficient withholding of Maryland tax. Add four quarterly estimated Maryland tax payments on non-extended due dates (4/15/2022, 6/15/2022, 9/15/2022 and 1/15/2023) that together with the W-2 withholding result in no tax due and underpayment penalty assessed. Then change the estimated tax payment dates for Q1 and Q2 to the extended due date of 7/15/2022 and see how this causes the Maryland Form 502UP to be generated and the underpayment penalty calculated in the PDF of the return saved by TT.
