The following diagnostic is generating:
Because the estimated tax is less than the estimate threshold, estimated tax vouchers were generated to avoid underpayment penalty. This occurs whenever the estimated {CurrentTaxYear} tax, less expected payments exceeds $1,000. For more information, please refer to the calculation or the note on the {NextTaxYear} Estimated Tax Worksheet.
Solution:
The diagnostic is saying that they're not over the filing threshold for requiring estimates but we did the calc and between what they owed in XXtax and what they paid, there is over 1k. so maybe they wanna consider filing estimates. (If estimated tax worksheet is not generating force in screen 7, Force Federal Estimated Tax Worksheet checkbox)
