After you file

Thank you very much  @DanaB27, SUPER HELPFUL, as always! Just to clarify though, I did not “miss” filing the form on time. I just made an error to Line 2 of the Form 8606 when I filed it last year “on time”.

 

1- Does that change any of your answers? 

 

2- Does the penalty / request to wave the penalty also apply in a case like mine where I just need to “update” an inaccurate amount?

 

Thanks!
