Retirement tax questions

I went back and looked at the return again. And I apologize for my error.

I added my work wages 33332.00

And the unemployment 16858.

This totalled the 49190.00

Of which I owed 3710.

I paid 1444 thru my work.

And sent in all I had which was 2000.00

The IRS is showing they got my 2000.00 the day after I filed.

My issue now is..my income based on the tax law deduction of 10200 of the 16858 in unemployment monies is less than the 49190..yet the IRS sent me a notice I owe still another 267 , 273 actual based on interest and penalties..basically hasn't corrected my return yet? The computer said I owe this based on 49190 minus what I paid of the 2226.00 original taxes when I filed. UG..sorry to be a "whiner" and so sorry for the misunderstanding on the 1200..if I'd used a calculator I'd caught that.  My bad. Since covid I now work 2 jobs 7 days a week tryin to recover!
