You can get Form 2210 and 1040-X in fillable PDF fromat from IRS.
If you fill out Part 1 correctly you will confirm either TurboTax (zero) or IRS (not zero).
If you want to request a waiver of IRS's amount using 2210 Part II Box A,
or point out your result of no penalty, or both,
attach Form 2210 to Form 1040-X and mail it in.
Penalties:
1040-x Line 16: Subtract any penalty from the amount you owe reported on original 1040. (in your case Zero)
Don't try to include, but ignore, any new or changed penalty.
IRS will calculate your new penalty on their own and will bill you.
Note: when you are not changing any dollar amounts on your amending 1040-X, you can leave all the lines 1-23 EMPTY.
Don't even think about including your old 1040 nor your revised 1040 because the Form 1040-X reflects any changes there and becomes your new tax return.
