If I refinanced my home mortgage (and have 2 1098 forms), should I manually combine and enter as a single entry in Turbo Tax?

If you refinanced last year, you’ll have a Form 1098 from your previous lender and one from the lender you refinanced with. You’ll need both forms. 

Follow these steps to enter your mortgage information:

1. Gather all of your 1098 forms related to your refinance
   1. (the form from your original lender and the form from your new lender)
2. Grab a calculator and add together the box 1 amount from each form.
   1. Enter the total in TurboTax as Box 1 Mortgage interest.
3. Add the Box 5 amount from each form and enter the total as Box 5 Mortgage insurance premiums.
   1. (If you weren’t required to pay mortgage interest, these boxes will be blank on your forms and you won’t enter anything.)
4. Add the property tax paid from each form and enter it in the Property (real estate) taxes box.

Next, finish adding info for boxes 2, 3, 7, and 11 using Form 1098 for the original loan.

What if I have more than two 1098s?

You should combine all of the 1098s directly related to the refinance and enter it as one 1098.  An example of this is if you refinanced two loans into one loan. Any 1098s not directly related to the refinance should get entered separately.

What do I do if I have multiple 1098s from refinan... (intuit.com)

other posts on here say only to do what you posted if the loan is above 375k? which is correct?

The loan limit would be $750,000 for loans after 12/15/17.  If your loan balance exceeds this amount, you deduction would be limited.

Multiple 1098 forms

Limits on deductible mortgage interest

This is a known issue that Turbotax is attempting to suppress rather than fix

I refinanced my home (value over $375K) in 2020 and have followed these instructions to sum up the 1098s.  My remaining question is: what/who to list as the "Lender" for this combines 1098?  As of now, I've called it "Multiple Lenders for Home over $375K Refinanced in 2020."  Will that pass muster, or should I put the name of one of the lending institutions... and if so, which one?  Thanks!

If you have multiple 1098 mortgage forms, you’ll enter them one at a time. After going through the steps with the first one, you can add a lender when you get to the Mortgage deduction summary screen. (In the case of a refinance, it's best to enter the 1098 from your original loan before the 1098 from your refinance. 

But, if they're both from the same lender, and one of them has the “Corrected” checkbox marked at the top, enter the corrected 1098 and discard or shred the other one. 

i wouldn't combine these but to add these separately. 

Sorry, but I already went down the road you suggested before I realized that was not the optimal way to go in my situation.  I am following this advice from another expert on this forum (it's also spelled out directly in the TurboTax Help section):

I have done all that, but am stuck on how to characterize the Lender on this combined 1098.

FYI, in my case entering the three separate 1098s (original lender, institution the did the refinance and held the mortgage for a couple weeks, and the final lender that acquired the mortgage, all in Oct-Nov 2020) as you suggest, and answering the follow-up questions regarding loan amounts and payoff dates apparently fools TurboTax into thinking my home loan is for over $m1.5 (about three times the actual amount), which kicks in a significant limitation in the amount of mortgage interest you can deduct.  In my view it's basically a TTax bug and the combined 1098 procedure is a workaround.  Cheers!

I received 2 1098s from refinancing. I entered them both...until I noticed that one says property tax and one is box 10 other taxes paid. What is confusing is they are the EXACT same amounts. Do I add both or just 1?

@Pennycandy2  It's a valid question.  But only the financial institutions can answer it. 

They may have each paid half of your property tax resulting in the equal numbers.  Or paid two separate years - one on time one early or late.  Or they are reflecting the same amount - one showing the taxes that they paid the other showing the taxes that they didn't have to pay.  You'll have to check with the bank(s) or find your escrow statement(s).
