Retirement tax questions

I thought that the "contributions made on your behalf to retirement plans"  refers to the 2-3% employer matching amount, not the employee contribution.  In this case, being self employed I contributed both the employee and employer match.   The employee contribution isn't made on my behalf, it is made by me. 

 

Can I ask another question about how TT treated earned income: In the QBI form, it shows my earned income as a negative amount, and a negative carryforward.   Why a earned income as a negative amount, and where could the negative carryforward come from?

 

thanks for your help.
