Form 8889, Part I

Hello,

My husband and  I are retired and have been through 2021.  We are on Medicare.  We have an HSA from when my husband was employed and had an HDHP.  I have always filled out Form 8889, but this year we were unable to contribute to the HSA, but we did have distributions.  How will I fill out Part I of Form 8889 for tax year 2021.  Do I leave it blank?

 

Thank you
