Do I include future contributions (not yet made) to my Roth IRA when reporting the value of my Roth IRA as of December 31? If so, how?

It says to include any contributions made after December 31 that were designated for that tax year (2019).  This also confuses me.  Do I start with the Dec 31 value and add the contributions made after (disregarding other changes in value after Dec 31)?
