Refund amount changed after filing

Hi.  Any feedback will be much appreciated.

I e-filed on March 6 and IRS accepted my return with a specified refund amount.

Today, I opened TurboTax and as always did some updates to the program.  Once I opened it, the refud amount decreased by around $1,400.  I opened the forms and went line by line comparing to the PDF file from the e-file and noticed that the "depreciation deduction" was lowered on some of my rental properties.

Any idea as to why this happened?
