When will the amendment option be available to use again and not being updated?

[SharonD007]

The 1040X used to amend your tax return should be ready by the end of next week.

You won't be able to file an amendment until your tax return is fully processed and you receive your refund or your balance due is deducted from your account. 

You can check for Forms availability by reviewing the TurboTax article When will my individual tax forms be available in TurboTax?

For more information and instructions, review the TurboTax articles How to Correct Federal Tax Returns, How to File an Amended Tax Return with the IRS and Video: How to Amend Your Tax Return.
