The important thing here is this: *PAY* *ATTENTION* *TO* *DATES*.

Thankfully, you're using the CD version of TurboTax, and I know that since you're working on 2018 taxes.

Enter each home office one at a time. Since each home office is located in what was your primary residence at the time, dates are very, very *VERY* important. That flat out:

 - Can not overlap

 - Can not be for dates the property was "NOT" your primary residence.

 Assuming you started 2018 with a home office in a primary residence you were renting and did not own, make sure you specify that you do *NOT* own the home. Then you will have the opportunity to claim a percentage of your rent payment as a business expense.

- you *MUST* show the closure of the first home office *BEFORE* you can "open" the 2nd home office.

- Your closure date of the first home office "MUST" be your move out date or a day before your move out date.

 - Your open date of the 2nd home office:

 - Must be at least one day "AFTER" the close date of the first home office.

 - Must be at least the move in date to the 2nd home or after.
