Beside my own mortgage lender 1098, I receive a 1098 for the co-op building's underlying mortgage. I discovered that both the 2022 and 2021 statements issued by our current management company's accountant had the incorrect TINs (SSNs). Since the real estate taxes and mortgage interest is calculated by amount per share multiplied by # of shares, the values are universal for all shareholders in the building and therefore I can input the correct values into TT. After contacting my management company to correct the TIN, they'll issue a new 2022 1098.
Now, do I need to do anything regarding last year's (2021) filing? Again, the values are correct, just the 1098 had the incorrect TIN.
