State tax filing

For this year 2019 I did enter the locality taxes in the w2 section and not manually in the form.  In prior years I did not enter the locality taxes in the w2 section or on the form.  Can I file amendments for the prior years?

Also would I start amendments with the earlier to present or present to earlier?

Is this better done by a professional or can I do it on my own?

Thank you.
