Yes, if you e-filed without meaning to, and now you are trying to fix it, you are amending your tax return. It's normal for the refund to go to zero when you start an amended return.
The original return and your amended return are processed separately.
For example, you do your return, and it shows a $1,000 refund. After you e-file, you realize you have another W-2 form. You amend the return. When you start the refund goes to zero. After you add the new W-2, it shows a $20 refund.
In this case you will get the $1,000 refund and an additional $20 refund.
If the first return you filed isn't right, you should continue with your amendment and make sure it contains all of your income, credits, and deductions before submitting it again.
