Tax Extender Amended 2018 Return

Hello,

 

Just received the email that the 2018 TurboTax version was updated with the information for the Tax Extenders.  I opened up TurboTax hit amend and it populated with a new refund number. Is it really that easy? I know I have to print, sign and mail the return myself but is TurboTax really that good? While it is an amended return I didn't physically change anything because the info was loaded already when I filed.

 

Anything I should look out for? Thanks!
