Can you help me on my 2016 tax filing. I paid for this service and my case number is 266227.

My audit assistance code for 2016 is 266227.  I received an IRS audit letter 2626c stating a finding that there was a problem with my tax for 2016.  I need to know if I made an error and need some assistance.  Can you help me? I treated a hardship loan that I took using money from my IRA account, which I am paying back bi-weekly.  I entered this on my 1040 as a rollover and I need to know if I did this correctly.
