Retirement tax questions

@dmertz   This is the question that I'm stumped when I reach.  It is the next question after I answer "Yes"  that I rolled the money to a Roth.

My employer allows me to contribute after-tax money to what is called "Company Savings Plan" in addition to 401-K.  I then can roll the after-tax money to a Roth IRA since they allow in-service distributions of the after-tax money.

The line "These would be contributions you made into the plan yourself, rather than being made by your company on my behalf  (This is not common)."  I'm not clear on what they are asking.

The company withheld after-tax money from my pay check and put it into the after-tax savings plan.  Is this considered contributions I made to the plan myself?  I didn't contribute any money to the plan outside of what was withheld from my pay check.
