Sorry for the delay --- unlike FBAR and FATCA reportings , the gifts/ bequests reporting requirements do not restrict themselves to "cash" or "financial assets" but "of value". Thus the reporting covers all items of value. So in your case you will have to report the aggragate value of the cash and realestate.
The date of acquisition/ transfer is simpler if you just follow the bank reporting date -- the date of death of the decedant.
Another item to note is that value ( in US $ ) of the condo on the same date should be recorded because this is your basis in the property when you ( at some future date ) may dispose off and have to pay the capital gains tax to the USA ( and to Germany ).
As far as filing electronically -- 3520 should be there in TurboTax. On the otherhand, nothing stops you from filing the return without this form and separately file the form 3520 --- however it is safer ( and generally expected ) to be filed together.
