Not sure about them asking for your SS #. If they have it (I never gave them mine before) they would only ask for the last 4 digits NOT the whole #. It doesn't sound right to me. FB Messanger? I don't do SM but I do know it is from others it just does not seem to be something TT would be doing. I my be wrong since I don't do FB and I wouldn't do it there anyway. How would you know it was them. How did you get them on FB?
If you have all your info then I would go for doing your taxes in one shot. Just remember to NOT close the program. Make sure to save ALL .pdf files and print the forms needed to file so that you can mail them if you have to before you file them electronically. I do not know where you are at in the process but you can always start from scratch and just let TT take you through it. If you have the TT from last year then the .tax file is there on your comp somewhere and when you first start TT it will go find the file and pull info from it and then also ask you whether you still need some of the same things again. Whatever you do DON'T CLOSE the TT till you are sure you are ready to file one way or the other. It is going on 2 months past the IRS filing date.
If you have someone in the U.S. that can call TT for you from here and you can FB messenger with them at the same time you might be able to get somewhere with that. Sort of like a 3 way call. Just make sure you can trust them with any info TT wants and send it to them ahead of time by a safe method. Just another thought to get around your contact issue with TT.
I think you will be fine if you just do it in one shot though. Good Luck
