My clients are getting dumber the closer it gets to the 18th.   Today client dropped off expecting it to be done by 18th because he will owe. Says he received  IRS letter changing the  2020 refund applied to 2021.but didn't bring the IRS letter .... can't I just go on IRS and magically find that.   And he made some of his estimates but not all...thinks it was $xxx or maybe $xxx. Do I need the exact amount?     AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!
