After you file

if the amended was accepted, then the delay may be caused by the IRS having to process the original before it can process the amended.   Getting the amended before the original  is fully processed would likely delay any refund shown on the original.  the general advice for amended returns is to wait until the original is fully processed before submitting an amended return. only the IRS can tell yo what the status is.
