Greetings Trixiebytes,
Welcome to the Apple Support Communities!
I understand that you would like to recover the most recent information from iTunes on your Windows computer and put it on your new iPhone. It sounds like the best process for you in this situation would be restoring from a backup, if iTunes backed up your old iPhone.
First, take a look at the attached article below that explains how to check and see what backups are available to you in iTunes.
Find and manage your iTunes backups - Apple Support
If you do have a backup available that you would like to use, please read over the Restore your device section in the attached article for how to complete this restore from a backup process.
Use iTunes to restore your iPhone, iPad, or iPod to factory settings - Apple Support
Cheers,
Joe
