403b Contribution Aggregation Question


I have a 403(b) plan at my day moonlighting job, to which I am planning to max out on employee contribution this year $19.5k. I was reading the IRS rules regarding maximum contribution limits, and there’s one part that’s confusing me. (I have attached the IRS rules sheet.). If you look at “chapter 3; Limit on annual Deductions”, it says that, since I have a 403(b) at work, I have to combine all the contributions that I make to ALL my plans (including my solo 401k for my SE job), to determine my MAC. Is that true? if so, will is still be able to the mega backdoor roth conversion in my solo 401k and max out at $58k in that account? Or will it be less than that?  viz, 58 -19.5= 38.5 k? Here is that paragraph: 


The rule discussed in the above Publication 571 deals with the control group regulations and comes into play if you are an owner/in control of a business that sponsors a solo 401k plan and the 403 is an annuity contract.  The 403(b) contributions to the annuity contact would be required to be aggregated with the contributions the self-employed individual makes to his or her solo 401k plan for purposes of the 415 annual additions limit
