2021 VA Form 760C Anomaly/Error on Line 10, column B

TT incorrectly populates prepaid taxes on Line 10 for period June 15, 2021 (column B) in Virginia 760C form (Underpayment of Estimated Tax). Instead of placing the appropriate value into column B TT adds the value to the prepaid taxes for period September 15, 2021 and puts the sum into column C while keeping column B empty. 

This error results in incorrect calculations for tax underpayment for the period and therefore in incorrect calculations of additional taxes (penalties). 

 

I request TT to investigate and and resolve the problem.
