I have not received a letter but I was able to setup a profile on the IRS website called secure access, by verifying a credit card, my address, my filing status, my cell phone number, the email I used for filing and I was able to view past years of transcripts and this years wasn't yet available but there was a note under the 2018 stating information was sensitive and as if nothing has actually been processed or I was unable to check just yet. After signing up for this it did state that it was unable to give me much info since its down certain times of the day and on Sundays. The site actually told me to try back with a different browser or to check back. So this has giving me a little bit of hope. On WMF online it does state the amount I am expecting and everything except the actual bar itself. Just the message unable to give any information on refund and the tax topic 152. Then in the smaller paragraph just if I have any questions the IRS number plus the code 9001. I have seen other people with the same thing and tax topic 152 but not the 9001 they did file 2/10/19 and I filed on 2/3/18 and was excepted the same day. I think the higher refunds may just need a simple verification or nothing can update because it is still to soon. Just like the IRS states they can not release any refunds with EITC until Feb 27th but updates would be after the February 15th. I do this to myself every year it seems.
