I got brave and downloaded the 2021 ProSeries program at the end of the day yesterday.  This morning I tried to open the 2020 version and had the fun of playing waiting for a text then waiting for an e-mail and then waiting for a text, etc, etc.  It looks like it is going to be another loooooooooong tax season😧
