The only workaround I know is FedEx instead of USPS.Quote from Btruck:
I used Investotek, which is just a file conversion program that allowed me to import my trades directly into TurboTax. It worked very well.

But now since I have 38 pages of trades Turbotax won't allow me to e-file so I have to send it via mail. Anyone know of a work around?
