601ERRV:2, FilingHdr_6 - ?:? - Invalid Agency ID. Received '30'. Contains invalid characters

Add a US phone number for the Turbo Tax profile.  You need to click Intuit Account in the lower left of the Turbo Tax page and enter a U. S. phone number and then your password and save it.  I don't even think it needs to be a valid phone number because when you go to file the return, it gives you an option to get email updates and/or text messages.  Just make up a U. S. number if needed and don't check the box saying you want text messages and you should be able to get the taxes filed.  

I have a US phone number and i still get this error code. have tried edge, chrome and explorer, same error code every time

I am getting the same message.  Phone numbers all populated.  Was anyone able to resolve this?

are you using a burner phone or possibly TracFone? 

My daughter and Mother have been getting this same error all day long. I have double checked both returns and nothing is wrong with the returns. 

I have same message and I am frantic.  I also entered phone number as advised. Please help! No post office open now!

Same issue. Cleared cache and cookies, used standard US cell phone. No joy.

did we figure this out yet ? i went through the whole return cant find anything wrong

Talked to phone line. No joy. Wait 24 hours.

If you're filing both federal and state, change state to 'e-file later', then e-file just federal. Then e-file state separately. My state has separate property tax form, and that one didn't go through, but I got both the federal and the state returns e-filed separately, so the error is in the property tax return form somehow.

Was able to efile federal return separately from state return.  Was successful by efiling federal return, and then the state return.  This was for a MN state return. 

There is a property Tax return in addition to the state return, the MN property tax return still would not get e-filed. Agree with previous comment the issue is somehow with that form, have never been able to e-file that item before, was always an extra print and mail.... 

Would've been nice to know that a few hours ago TurboTax... but thankful another member pointed out the solution!!!

Next day wait did not work, but e-filed state and fed together, and did print for MN Property Tax. That worked, thanks to the community for figuring out what intuit could not.
