TaxCaster 2021 seems inaccurate.

Hello,

 

Taxcaster is showing a roughly $540 tax balance due with $13,500 net self-employment income, and the $1,400 stimulus for 2021. This seems far lower than what I had estimated (~$2,000). I'm single, mid-30s, with no dependents.

 

In the summary I see ~1,900 in federal taxes minus ~$1370 in credits.

 

I also run this through TurboTax 2021, and got an even lower estimate of $250 due, with possibly slightly lower net income.

 

So I guess my question is, are these at all accurate estimates?
