Form 2210, Line D, Incorrect Q2 dates

I am using TurboTax Deluxe desktop for Mac.  When submitting my information for Form 2210 (Underpayment of Estimated Tax), I am entering the actual withholding I paid through the year.  However, for Q2 withholding, the program is asking me to calculate the withholding as amounts I paid from 4/16/23 - 7/15/23.  For Q3 withholding, the program asks for amounts paid from 7/16/23 - 9/15/23.  

 

The ACTUAL dates on the IRS Form 2210 are 4/16/23 - 6/15/23 and 6/16/23 - 9/15/23 for Q2 and Q3, respectively.   It seems that this is an error in the program.
