Roth Conversion- deductible and nondeductible contributions

In April 2019 I converted my traditional IRA which had a balance of  ~$20K ($5500 nondeductible, $14.5 deductions contributions). I do not have other traditional IRAs (zero balance).  I made the $5500 nondeductible contribution for 2018 tax year and forgot to report it on the 2018 tax return.  I know I have to amend my 2018 return to report.  I have no previous nondeductible contributions. I assume that once I amend the 2018 tax return, I can report then report the roth conversion which has both deductible and nondeductible on the 2019 return in TT.  How do I report this type of roth conversion in TT?
