I am wondering if HR Block automatically handle waiver (form 5329) in electronic form or do I have to file something separately by paper?
UPDATE
OK, I realized that the program is calculating RC, but I am not entering the input properly. I think one of the confusing is due to the "correction Window" and why there is a separate a and b line for 52 and 53.
first it ask about what the RMD should be:

The first question is obvious, you enter what your RMD should have been for the year. I am not certain how to answer the second section. It ask if I received a distribution of excess distribution from any qualified plan durign the correction window? So in my situation, I discovered I underwithdraw the RMD due to a transaction error but corrected it in Jan of next year. The correction window appears to the year after the tax year so the correction withdraw should be within this correction window. My guess is that I click on Yes, but I am not sure what I should be entering in the required distribution(s) that were distrigbuted back during the correction window. Do I enter the amount I withdraw in the correction window?
In the second HR block page,

It's not clear what the first field is asking. Is this the distribution on just the withdraw during the correction period or the RMD I did + correction? The second field is not clear, but I think it means all other plans which include non-qualified plans.
Here's the actual IRS Form 5329 section

I am guessing that the 52b and 53b are zero because I don't have have non-qualified plan. If I look at previous 5329 form I do not see a separate a and b split. Was this just added during secure act 2.0?
Update2
Still waiting for a response, but I think I figure out the entry on the form.
- I will use 52a and 53a to enter the expected RMD and actual RMD. 53a and 53b appears to be for non-qualified withdraw.
- Let's say I am supposed to withdraw $10K last year for RMD but only withdraw $3K, then I would enter $10K on 52a and $3K on 52b. Let's say I just withdraw the remaining $7K this year to cover the shortfall, there is a 10% penalty on the $7k shortfall because it is withdraw within the 2 year window which I can try to waive with a letter.
- The penalty should show up in line 55 where we would enter "rc", this should eliminate penalty until IRS either approve or deny it.
I am wondering if I can just delete the Form 5329 and just submit that separately.
