In 2017 I rolled over my 401k from my previous company into an IRA account. Is tax reporting required for the IRA account and what do I need to report?

In March 2017 I rolled over my 401k from my previous company into an IRA account. I did not receive any distribution from the rollover. The funds show up as a "Rollover IRA" account in Fidelity. 

1. Do I have to report the rollover. On what form is it reported on? What form should I receive for the rollover? 

2. Do I have to report any gains/losses for the Rollover IRA account and pay taxes on it for 2017? On what form to report. What form should I receive for the account?

3. Do I have to report any gains/losses for the Rollover IRA account and pay taxes on it for subsequent years? On what form to report. What form should I receive for the account?

Your responses to the questions are appreciated. Thanks!
