Inherited IRA converted to Roth IRA not showing on form 8606

Converted part of the inherited IRA  from my late spouse (died 2018) to Inherited Roth IRA for 2022 but this was not showing on Form 8606 on Turbo Tax.  May I know if this should be showing in this form?  The distribution on the 1099 R shows on box 7 as 4.  Is this the reason why this is not showing on Form 8606 even this was converted to Inherited Roth IRA?

 

The only one that was included on Form 8606 was the distribution that I have converted to Roth IRA  from my own traditional roll over IRA which the 1099 R written on Box 7 as 2 which is correct as converted to Roth IRA.

 

The 1099 R with No. 2 on Box 7 was included on Form 8606 while the other coming from inherited IRA with No. 4 on Box 7 was not included.  Is this correct?

 

I really need help!
