Retirement tax questions

I called Fidelity, they say if it’s an excessive contribution I need to go through my employer. I know how hard it is to deal with the employer on this, they probably will say it’s not their fault and won’t help:)

 

the only other option is to do a plain with draw, but two issues come out: 1. My 401k has pretax and Roth money in it, withdrawing might be proportional, but not sure yet. Will this be a problem?

2 I will get an 1099r, which will be taxable if I report it. So I should just ignore that 1099r then?
