If you use TurboTax Full Service- Audit Defence is included and they will be responsible for getting everything completed for you if something happens that you need to do a ReFile. 

You will send your tax expert all the documents/ information requested to file your return. 

Thank you for choosing TurboTax. 

Thanks a lot for your reply.

I'll rephrase it, because my question wasn't clear, my bad. 

I would like to file my taxes before the 17th but I already know I'll need to refile them in a couple of months because I'm missing some documents and I can't get a copy right now.

In that case do I need to repay for the service?

Thanks a lot

No, you won't need to repay.
