Get your taxes done using TurboTax

look at check box "D" under Part II of Form 2210.......I think that accomodates your issue.....

 

from the instructions: 

 

Section A—Figure Your Underpayment
Line 10
Enter on line 10, columns (a) through (d), the amount of your required
installment for the due date shown in each column heading.
For most taxpayers, this is one-fourth of the required annual payment
shown on Part I, line 9.
However, it may be to your benefit to figure your required installments
by using the annualized income installment method. See the
Schedule AI Annualized Income Installment Method instructions, later.

 

then see page 8 of the instructions for Schedule AI
