Unfortunately for you, TurboTax Online makes it difficult to attach Form 5329 in your situation.
The proper way to file Form 5329 is attached to Form 1040-X.
After you e-File,
get Form 1040-X from IRS website and mail it in with your 5329 which you can also get in fillable PDF.
Note: since you are not changing any dollar amounts on your amended tax return, you can leave all the lines 1-23 EMPTY.
Part III explanation: will explain to the IRS why you missed the RMD, what action you took that they should waive your penalty. this is required if you request a waiver.
You will have to mail it so this does not use up your one 1040-X e-File.
done this way, you sign 1040-x, not 5329.
