Efile transmission not going through, error code 2

[JTLaur]

Changing the Security settings (including turning off firewall entirely) did not work, still seeing Error 2 for the ~50th time.

I am using the installed Desktop edition, TurboTax Premium.  I don't understand all the comments about "uploading" PDF files - I didn't upload anything, TurboTax made all the files for filing. Hence I don't see any way to reduce the size of the file that is internal to TurboTax.

Anyone using Desktop (not browser) found an answer to this, a way to get around the Error?

Today is tax day, and I have been trying to get this working all last evening. I need to get this figured out!

I had this same error yesterday, 4/14/25 and again today. I was able to send just the federal (I removed the state from file temporarily). However, I’ve not been able to send my brother’s federal or state.

I’m using Desktop Deluxe and have no attachments nor exceptionally large returns. Thank you to the person who said I couldn’t file the state until the federal is accepted.  I’m still not able to file my brother’s federal and state.  It’s just strange they have had this problem for months and not added capacity.

I already went through the options in that thread, before I wrote my post.

- They are attaching PDF files, so I assume they are using browser. I am using desktop version. I didn't attach anything.

-  I tried changing the security settings discussed (as I said in my post), they didn't help.

-  I saved, closed, reopened TT, ran update (none found). That didn't help.

Q: Is there a way to reduce the size of the file that TT is uploading in the Desktop edition?

What do I try next?

I am only e-filing Federal (VA state not due till May 1).  

I have been using TurboTax for probably 20 year; this is the first time I have had this. But I see other posts going back at least to 2019 and 2020.  Agreed, they should have figured this out by now.

@ClassyPenguin can you please rerun your Federal and State reviews and try again? Thank you!

I will.  Thank you.
