Good evening, @ekaye7497.
Thanks for posting your question here.
While we do have several options available for e-filing taxes, you may benefit from speaking with an accountant regarding which option would be best for you and your business type.
For now, you can refer back to Intuit TurboTax's website for plans and prices since you've already mentioned having QuickBooks Online.
Also, for more information about QuickBooks Online plans, here is a helpful article: QuickBooks Online Plans and Pricing.
If you have any more questions, please don't hesitate to comment below. Happy Monday!
