MO state department has hold my state tax from past 2year.they are saying that I have a withholding amount and I owe money to them.I might have filled in something wrong?

If there is no withholding amount you will owe.

file an amended state return attaching a photocopy of your W-2 showing state tax withheld. Start with 2018 earliest year.

you must do that within three years of filing.

Sir/Man,

              Thanks for your response. Will you please explain me in depth how to check W2 showing tax withheld and how to file an amended state return? And I have only 2 years of filling 2019 & 2020. 

I have send the attachment of chart that Mo state department has send me. Thank you

The amount of tax withheld from your pay may not necessarily cover 100% of the taxes you owe.  Taxes withheld rarely are an exact match for taxes owed.

Now please suggest me what  am I supposed to do how can I solve this. Please help me.

If your employer verified that your W2's were correct, and if you entered them correctly on your tax return, and if you're pretty sure your tax return is otherwise correct, then you should pay the tax bill you received from Missouri.

Actually i am really not sure whether I filled it right or wrong. Will you please help me to check whether I filled my returns in right way or not. I really don't have any ideas on how to check our returns. Thank you.

Unfortunately no one here can see your tax return.  And no one here can know whether you entered all your required information into your tax return, or whether you entered it correctly.  You may have to seek other assistance.
