1099 G from the state of mississippi shows box 2 amount of 2068, but in box 3 states amount is for year 2019'

If this is the form you received in 2021 then it is either incorrect or actually for 2019 but was paid to you in 2021.  You need to contact the state to verify if the year 2019 is correct and why you received this form.

This issue may not be resolved in time for you to file your taxes by the April 18, 2022 deadline.  You may want to consider filing an extension to file you’re your tax return.  This TurboTax link How do I file an IRS extension (Form 4868) in TurboTax Online? will assist you in filing an extension.

IRS extensions for tax year 2021 must be filed on or before April 18, 2022 for domestic taxpayers.

Keep in mind: An extension doesn't give you extra time to pay your taxes — but it will keep you from getting a late filing penalty.

Thanks,  

1099 G very clearly has this year on the form but says for tax year 2019.  It is the amount I received in 2019 for my taxes.  I will call the state and verify from my 2020 taxes that I have already paid on this income.  

Thanks
