After I entered deductions for property tax, mortgage interest, I got a message stating tax break still under review though keep going. Can someone further explain?

I completed my return though saw no impact to return once I deducted my mortgage expenses.  I have a 2nd home too that I declared as a rental.  The taxes and interest were deducted for rental, just not on my primary residence - between both properties, I did max my deductions at 10 grand.  I'm confused though the rental took the deductions and my primary residence saw no change to return.   My primary home was newly bought in 2018 and only lived in for last 2 months of 2018 while I still had to pay full year of taxes.  I was thinking id be able to deduct at least.   Tried calling though 2 hour hold was all I could take.
