Missed my 6 month STEM OPT Extension reporting deadline

I am on STEM OPT Extension and I missed my 6 month reporting deadline. I reported it a month and half late and I contacted my DSO for help and they told me that the window to upload is closed. Now they have added a note to the portal that I have reported but it's past due.

I submitted my 1 year employer address reporting and 1 year student progress report (pg 5) on time. It's been 8 months since that incident and there has been no issues with my SEVIS.

I got picked for H1B now and I am worried cause of all the SEVIS terminations that is happening in recent times, do I need to inform my employer or do I need to contact an immigration attorney before submitting my H1B petition. Is there any risks or issues that might come cause of this and any advice would help
