Sorry, no one at the Answer Xchange can do that for you. You have to purchase and download the desktop software yourself. If you already paid for Self-Employed then customer support can push a download to you, but they are closed for the holiday, and will re-open on Wednesday, January 2.

They are available from 5 a.m. to 5 p.m. Monday - Friday Pacific time.
If you did not already pay for your 2017 software, then you will need to use a credit card to pay and then download it.
When you complete your 2017 return, it has to be filed by mail. When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS and/or your state received the return.
