@fkhalilz , line 54 has two parts --- (a) yes/no for multiple donors and if related and (b) information about the gift itself.
(1) In your particular case , it was inheritance triggered by the death of the decedent ( donor ) and therefore the gift date is generally the date of passing or when the Estate disbursed the amount. It is not the date when you transferred the amount to your US account ( generally speaking ). So either of those dates should meet the requirements of the form 3520.
(2) line 56 is not applicable to your since you received the amounts from an estate of the decedent ( not a corp. or partnership / business entity ). Even if the decedent had put everything in a revocable trust, it became irrevocable on the passing of the decedent and probably folded back into the Estate.
So answer should be NO
You mention the monies were wired / transferred to your US bank account in portions to meet the requirements of local conditions / restrictions. Here you should note that if the monies rested even for a day in an account over which you have signature authority, the amount may be sufficient to meet FBAR ( form 114 at FinCen.gov ) and FATCA ( form 8938 ) regs,
If you want more info on the 3520, please consider reading through the instructions for form 3520 -- >
