Looking for accurate tax calculator

I am self employed and moved to Florida from another state end of 2022.

 

I have been looking for a calculator that can tell me the amount I will owe at the end of 2023.

i.e. the max amount from the assumption of having zero write offs.

 

I've used the IRS estimator form and 5-6 other calculators.

Each one gives me a completely different answer... is there one that is reliable?

Since I'm filling out the IRS one myself I feel like there's room for error on my part so would prefer an automated one.

 

Second to this on some of the calculators it shows fed tax estimated due and on others it shows fed and self employed tax due... there was a $20k difference between the two results.

 

Any recommendations would be appreciated.

 

I also understand that turbo tax will estimate taxes, however this is my first year going into self employment entirely so historically my income has been different... unsure how accurate it will be.
