Retirement tax questions

I have the same question. Doing a early assessment of my 2020 taxes, basic taxed owed was about $250, when I added both stimulus amounts (1st @ $2300 2nd @ $1100), my taxed owed jumped to $3614!! Here again, we, according to the stimulus program this distribution was to be untaxed as income, but it's being taxed as income otherwise I wouldn't see such a significant jump in now owing. So either we were lied to or TurboTax has a glitch in this programming. please explain.
