Get your taxes done using TurboTax

For those who finished all these nightmare can you share how you mailed the 3520 to IRS P.O. Box? 

does it take FedEx overnight? It has our social security number so I don’t know if it’s a good idea to go with USPS.

 

The IRS website says you could use private delivery service for your return but I’m not sure about 3520
