The due date showing in this worksheet populates as 5/17/21. Needs to be updated for the 2021 returns which are due 4/18/22. I do not understand why it is so difficult for Intuit to change due dates in the software. This is a big problem lately. Please be attentive to due dates that are involved in calculations and error messages. Intuit doesn't seem to understand that due dates in the software need to be correct. Where is the quality control for this product?
