Thank you all for your help... I believe the 2014 1040-X was processable because none of the 1040-X's for the years 2015 thru 2017 included a new 1040, and they were all processed and additional refund checks were issued. I use this logic because the initial mailing of four years of 1040-X was made in one envelope with a cover letter detailing what was being submitted. However, my follow-up question now would be...

I checked the link and could not find any example identical to my situation, so since I received a refund after the 1040 was filed, isn't the filing date of the 1040 considered the date when the tax was paid? I say this because technically when the estimated or withheld tax was being held by the IRS, it did not become the property of the treasury until the tax return was officially filed. To look at it from a different angle, the original return was not due on 4/15/2015 because I anticipated a refund and there was no tax due. Indeed I did not have to file any return at all, but had the option to file within three years or forfeit the refund. I have a feeling I am being a devil advocate, but it doesn't hurt to ask. I appreciate your patience. Thanks again.… within two years after the date they paid the tax
