Have 3 clients who were LLC's filing schedule C in 2019 who are S-corps in 2020.

All received PPP based on schedule C numbers (banks were fine with this). For payroll costs and owner replacement during the 8-week PPP period, should these be ideally run via payroll or done via the 8/52 owner replacement? 

One is running payroll and two are just getting going. Thoughts and friendly advice is appreciated.
