I used to not practice Islam for years. I am practicing now alhamdulillah. Do I need to estimate and make up my Salah, Fasts, and Zakat? Also when I begin practicing, in one salah I intentionally skipped first tashahhud because I thought it was mustahab. Do I redo this specific salah?

I need more info. But repeat that salah, pay your zakah and make up ur missed fasts
