Recovery rebate credit issue
Long story here, hope someone can help. I'm eligible for all 3 EIP payments. The 2nd one and the 3rd one arrived by paper check no issues. However, the first one I had to have the IRS perform 3 seperate traces as the check had not arrived. After 6 months and concluding the traces (green light) the IRS informed me to claim the $1,200 as a recovery rebate credit which I did using Turbo Tax. After a 3 month wait it's now showing on Where's my refund that the IRS reduced my credit from $1200 to ZERO, noting that there may be a calculation error on the return which was done using Turbo tax. In addition IRS will send the notification letter out on August 30 which could take at least 60 days to reach me abroad because the mail is being held up by Covid. I understand I only have 60 days to reply to their notice that may not arrive for 90 days. Im in a tough predictament. I have nothing to go on accept a calculation error when claiming the credit. All of the requirements I fall under. Single filer, no kids, under 75k. Perhaps a line 30 error? And no one claimed me as a dependent. I just dont get it. Did turbo tax make an error when sending it off? Any suggestions and help would be greatly appreciated. Thank You
