Business & farm

Thank you so much VolvoGirl for your reply.  I am sorry that my question was not clear.  In the State filing, on the page "Annualized Income Method" there is this question "Did you earn your income unevenly during the year?"     If I answer "NO" it says "Request for Penalty Waiver"  which doesn't apply to me .

If I answer "YES" which does apply to me ,  the following Table is displayed for State AGI Adjustment. 

First Quarter (01/01/19 to 03/31/19)
First 2 Quarters (01/01/19 to 05/31/19)
First 3 Quarters (01/01/19 to 08/31/19)
All 4 Quarters (01/01/19 to 12/31/19)

My question is what is the effect of completing this Table on the tax liability? Is this just for calculating underpayment ES? or the total tax liability is less if one has uneven income?   Thanks again for your help.
