Creaing a second, "fake" return in TT for next year's projections

I was thinking of creating a second return in TT for my 2025 projections after I finish and file my 2024 return. My filing status will change in 2025 (I was widowed in 2024) and some income will change next year. Conceptually, this could help me determine quarterly tax estimates, where I will be on the IRMAA scale, etc.  Anyone ever do this and was it effective?  Thanks!
