If you efiled the original return then you could wait until TT has the efile tool working for the amended return since the IRS is now accepting them that way ... don't know how long it will be until TT has it up and running ... could be a few days or weeks.
If you need/want to file it now ( be aware mailed in amended returns are taking 6 months or more to process) you will need to figure something out. Save the PDF to a thumb drive and see if a friend or family member can help or places like Office Depot can print things.
