After you file

good morning all, checked my WMR and it states mailed. reading through other intuit forums and found that the usps has a feature to track INCOMING mail! called informed delivery, (Informed Delivery® is a free and optional notification feature that gives residential consumers the ability to digitally preview their letter-sized mail and manage their packages scheduled to arrive soon.) i had never heard of this feature before , but i signed up. I also read that it should be about 3-5 business days for check delivery and that it comes first class usps (no tracking #). So i felt this was my best option to be informed of my refund. Just wanted to share my discovery, hoping it helps others!
