You may contribute to an existing IRA if you like.
Note, however, that an SEP IRA is a different kind of plan and would require opening a new account. The SEP IRA is an interesting idea because it has a much higher contribution limit than a traditional IRA, but you can only contribute 25% of your net earnings. So, whether an SEP IRA makes sense depends on your actual self-employment income.
