I recently finished work due to becoming pregnant and was told that I may be entilited to claim my taxes that I paid back - how do I go about this and will I be able to claim it back?

It depends on HOW MUCH you made, WHEN you earned it, your residency status, AND your Marital status, plus whether you had other sources of income.

A more complete posting of information would help in my analysis of your situation.

To get tax refund you must file your tax return. If taxes withheld are more than tax at per your tax return, you will get refund.
