Can I amend a return if I already filed

Can I add to my tax return if I already e-filed

Yes, but the amend form is not yet finalized in TurboTax so you will need to wait. You must also wait until your return has been fully processed and you receive your refund or have paid your balance due to amend. You will need to prepare an amended tax return on a 1040X and mail it in if the new info changes your refund or tax due amount. You cannot e-file an amended return.  They have to be mailed, and it takes up to 16 weeks for the IRS to process an amended return. 3 weeks after you mailed your amendment, you can start tracking its progress at the IRS Where's My Amended Return? site. 

Amendment instructions can be found here when they become available for 2017 (early february):   https://ttlc.intuit.com/replies/3288565
