Can I get some info and source on depositing more than 5.5k a year?

If you deposited nothing in 2018 you can contribute towards 2018 until April 2019, you can also contribute towards 2019 starting Jan 1, 2019. So for that overlap you can technically get 2 years in. But that's still only 5500 a year, so it's only useful to get started.
