I opened a ROTH IRA and contributed $5,500. I recharacterized to a Traditional IRA (because income limit), then i converted my account to a ROTH. How do I report this?

I opened a ROTH IRA and contributed $5,500 in 2018. I then recharacterized my contribution to a Traditional IRA because I exceeded the income limit for a ROTH IRA. I then i converted my account to a ROTH IRA, this was all in 2018. Now and at the time of conversion my account was at a loss for the year, so there were no gains when I did the conversion. How will I report this?
