How to take back money from non-deductible IRA

In 2017 my wife opened a traditional IRA account(fidelity) and contributed $5500 thinking she can save some tax amount but we it became non-deductible IRA (got form 8606).

 

She has already 401k at her employer but mistakenly opened traditional IRA account trying to save some money. She has no knowledge about IRAs.

Also she invested that $5500 on mutual funds and got some additional amount.

 

Now what are her options:

How can she take back that $5500 from fidelity traditional IRA account?

Or Can she convert to Roth without any fee.
