Question of MAX payroll tax as S-corp LLC

[James Chai]

i have single-member LLC rental generating income on the side operating as STR. From the single-member LLC, i pay myself 100k last year to max out on the solo 401k contribution, while still having a W-2 as an engineer as my main job.

my main job pays me 170k/year (Google)

my single-member LLC rental pays me 100k/year (as S-corp structure)

my question is regards to the payroll tax, i know I already max-ed out on the payroll tax on the employee side, any additional payroll side as employee will be refunded in my tax return, how about the employer side. Given that my W-2 employer (Google) maxed out on the employer side of payroll, anything my STR single member-LLC contribute as S-corp as employer, will that be refunded as well?
