Retirement tax questions

Thank you very much for this.  I can see how to enter it.   I have a few additional questions.  If you feel opening a new entry is best let me know.  I have been reviewing this process and I can see I do not know how well I accurately documented my contributions.  I started contributing to an IRA in 1982.  I opened a Dreyfus account and had the account until 1996 when I rolled it over to a new custodian (Morgan Stenley).  I have a rollover statement from Dreyfus but all other records from Dreyfus have been destroyed.  I have most of my documents from Morgan Stanley. Then in 1998 I converted my Traditional IRA to a Roth.  I have that dollar amount.  Would that be my basis for my Roth IRA conversion?  Then I need to add back my additional contributions over the years.   Should I document any comment to the IRS on this (the amounts and not correct so I updated them)?  Also I got married 2013 and never entered my spouse's contributions, so I need to add those in for them too.    Does this seem like a good approach to document my Roth contributions?
