I want to make sure with my Amend Return I won’t get late fees or charges for my original submission that was wrong .

TurboTax does not charge an additional fee for amending a return if it was originally prepared using TurboTax. However, if the amended return requires an upgrade to a higher version of TurboTax, there may be additional costs involved. If you used the Free Edition of TurboTax, you might face limitations when amending, and you may need to upgrade to a paid version to accommodate the changes.

if you owe the IRS will usually charge penalties and interest. if you're getting a refund there are no federal penalties or interest

There is no way to guarantee that the IRS will not charge a late fee or penalty. We don't know any of the details of your situation, but filing an amended return does not avoid penalties for having paid late or having paid too little on your original tax return. If your amended return shows that you owe additional tax you might be charged penalties and interest for late payment. If your amended return shows that you get an additional refund there will be no penalties or interest.
