update client cover letter

[susanholly77]

This tax year (2020) was a crazy tax year with all kinds of software changes needed throughout the tax season.  I think that the client cover letter should be updated when there are certain changes.  This year, as my clients are now receiving letters from the IRS regarding the CARES Act deferral, I feel that this information should have been articulated in the cover/information letters at the beginning of the return so that it shows current amount due, estimates, and deferrals due over the next two years.  This would have been helpful.
